👉 In meteorology, a barometer is a device used to measure atmospheric pressure. It works by sensing changes in the gravitational force acting on an object, which can be influenced by its weight and altitude.
The barometer uses two types of devices:
1.
Gage
: This type measures the change in the gravitational field due to air movement, such as wind or water flow.
2.
Pressure sensor
: This device detects the pressure difference between a fixed point (the atmospheric pressure) and an
barometrical
